The LMT01 is a high-accuracy, 2-pin temperature sensor with an easy-to-use pulse count interface which makes it an ideal digital replacement for PTC or NTC thermistors both on and off board in automotive, industrial, and consumer markets. The LMT01 digital pulse count output and high accuracy over a wide temperature range allow pairing with any MCU without concern for integrated ADC quality or availability, while minimizing software overhead. TI’s LMT01 achieves flat ±0.5°C accuracy with very fine resolution (0.0625°C) over a wide temperature range of -20°C to 90°C without system calibration or hardware/software compensation.

Unlike other digital IC temperature sensors, LMT01’s single wire interface is designed to directly interface with a GPIO or comparator input, thereby simplifying hardware implementation. Similarly, the LMT01's integrated EMI suppression and simple 2-pin architecture makes it ideal for on-board and off-board temperature sensing. The LMT01 offers all the simplicity of analog NTC or PTC thermistors with the added benefits of a digital interface, wide specified performance, EMI immunity, and minimum processor resources.
